You could not answer a question? What is "krupp"? There Is an opinion, what is it infektsionno-allergic disease, and exists " false krupp ".
P. S. If it is not difficult, more in detail!

Dear Victor! Really there are 2 kinds of a croup - true and false, both are characterized by display of an edema of a larynx (the infectious or allergic nature). The first develops at a diphtheritic infection, proceeds very hardly and always demands hospitalization. The second - "false", he - virus, proceeds easier more often and develops at respiratory infections, more often a flu caused by viruses and a parainfluenza.
